#1**+2 **

You probably already know that all the angles in a triangle add up to 180 degrees.

From the triangle, you are given two angles already! Angle P=42.7 degrees and Angle O is a right angle=90 degrees.

Add the two angles up and you get 132.7!

After that, do 180 degrees - 132.7 degrees and you get **47.3 degrees for Angle N. **Btw the answer is **a.**
